Hi everyone. I have decided not to wait for the Haswell refresh as I have lost my patience in the long waiting. At my local Apple store, I have the choice of a between a 2012 refurbish retina MacBook Pro with the spec of 2.6Ghz 8GB ram ssd 512GB ssd Or a new 2013 base model with 512 GB SSD upgrade. Surely the refurbish one is cheaper. However I was worry it will be a LG monitor as the first generation it is likely for a LG screen to have ghost image (image retention ). I was wondering if I can take it to the local Apple Store to ask for a replacement ?
